Abstract

Under normal atmospheric conditions, a uniform green covering layer, the so-called patina, forms on inclined copper surfaces only after exposure to the weather for many years. There has long been a desire to effect preweathering of the surface of semifinished products consisting of copper in the works on a large industrial scale, closely simulating the natural green patination. The method according to the invention for producing an artificial green protective and covering layer comprises first roughening the surface of degreased strip or sheet in a controlled manner by a mechanical treatment. In a further step of the method, the roughened surface of the strip or sheet is then treated in continuous flow with a suitable chemical reaction solution for green patination. After the chemical treatment, the strip or sheet is stored in its final dimensions for some time in an air-conditioned room.
